Now I am trying to hyphenize tags which have spaces, but if I do this:
{% set filter = p.taxonomy.prestation|join(' ')|hyphenize %}{{ filter }}
it outputs hyphens even between tags as shown below:
data-filter="sols-placo-peinture-cuisine-salle-de-bain"
Is there a solution to have hyphens only for tags, as following?
data-filter="sols placo peinture cuisine salle-de-bain"
I could not find out how to apply |hyphenize to tags only.
@brigaill, Try the following:
// default.md
taxonomy:
tag: [a, b, hyphenate me, c]
// Twig
{% set tags = [] %}
{# Step 1: Hyphenise each tag and add to array of tags #}
{% for tag in page.taxonomy.tag %}
{% set hyphenisedTag = tag|hyphenize %}
{% set tags = tags|merge([hyphenisedTag]) %}
{% endfor %}
{# Step 2: Join array of hyphenised tags #}
{% set filter = tags|join(' ') %}
<li data-filter="{{ filter }}"></li>
// Generated HTML
<li data-filter="a b hyphenate-me c"></li>
